A new delivery format does not establish a new benefit. NAD eye drops, suppositories, and dermal preparations require evidence and quality controls appropriate to their actual intended use.
Do not repurpose a capsule, oral liquid, serum, or nasal bottle for another route. Similar names and ingredients do not make products interchangeable.

Eye drops require particular care
FDA emphasizes that medicines used in the eyes must be sterile. A cosmetic eye cream is not an eye drop, and “NAD drops” may refer to an oral product. The sources reviewed here do not establish a consumer NAD eye-drop treatment for vision or aging. Discuss eye symptoms with an eye-care professional rather than experimenting with an unverified preparation.
What about NAD suppositories?
A rectal or vaginal route is not equivalent to oral or IV delivery. Ask the prescriber for evidence supporting the exact preparation and purpose, along with handling and administration instructions. A claim that a route avoids digestion does not establish absorption, effectiveness, or safety for a particular formulation.
Dermal and transdermal are not identical claims
A cream meant to change skin appearance is different from a product claiming systemic delivery through the skin. “Dermal Plus” or another trade phrase does not tell you which is intended. Read the full product identity and claims before comparing it with an injection. Our patch guide covers the missing evidence in many absorption claims.
Do special routes remove side effects?
No route name establishes the absence of local irritation, contamination risk, or systemic adverse effects. Ask what was actually monitored in human use and whom to contact about a reaction. If a product lacks clear directions or a responsible clinician or manufacturer contact, uncertainty remains unresolved.
What information should you request?
Obtain the exact ingredient list, intended route, concentration or amount per unit, product status, storage instructions, and evidence for the claimed outcome. For a prescription, use the dispensing pharmacist as the source of handling instructions. Nasal sprays, skincare, and oral supplements need separate comparisons.
